My friend has set up a web server over https with a self-signed certificate. I can access the site no problem (I just need to manually accept the certificate). When I go to download audio or video (or any files) from the server and check the download history the phone tells me it's "waiting for data connection". It waits for a couple minutes and then says "download unsuccessful". Is it possible to download directly from the web server or do I need to download to my computer and then transfer the files to my phone?
